Alexander I of Russia

Alexander I of Russia (23 December 1777-1 December 1825) was the king of the Russian Empire from 1801 to 1825 and King of Poland from 1815 to 1825. During his reign Russia fought in the Napoleonic Wars along with the Coalition and assisted the Greeks in the Greek War of Independence.

Biography
Alexander was the son of Paul I of Russia and cousin of Friedrich I of Wurttemberg, and became king when his father was assassinated in 1801 by soldiers angry at his reforms. A chameleon in his political beliefs depending on who was with him, he was not a good ruler, and under his first few years of pressure from the First French Empire he was defeated at the Battle of Austerlitz in 1805, in which he held personal command over the Russian army.

However, he became a mature leader during the second half of his reign, revocating many of his liberal reforms that he had passed in the first part of his tenure as Emperor. He defeated the French Russian Campaign of 1812 at the Battle of Berezina and won the support of his nobles. He also fought the Ottoman Empire and by the time of his death in 1825 had won several military campaigns.
